SPECIFICATION forming part of Letters Patent No. 688,613, dated December10, 1.901.

Application tiled March 7, 1901. Serial No. 50,221. (Nomodel.) V

To CLZZ whom t may concern:

Be it known that I, LYMAN II. EVANS, a citizen of the United States ofAmerica, and a resident of Des Moines, Polk county, Iowa,

5 have invented a new and useful Mop-Wrin ger,

of which the following is a specification.

The object of this invention is to provide improved means for wringingmops, and it is especially adapted for use in wringing 1o mops made oftextile fabric and carried in 'a mop-head.

A further object of this invention is to provide for the maximum openingof the wringer for the reception of the mop, whereby mops r 5 of thelargest size may be admitted, clamped, and wrung with the same ease andfacility with which mops of smaller size may be manipulated.

My invention consists in the construction,

2o arrangement, and combination of elements hereinafter setforth,pointed out in my claims, and illustrated by the accompanyingdrawings, in which--s Figure 1 is a side elevation of the complete e 5device. Fig. 2 is a plan of the complete device.

In both views of the drawings I show the wringer-rollers separated forthe reception of the mop.

In the construction of the device as shown the numeral 10 designates abase-frame comprising a curved body portion on an arc of such size as toconform to the curvature of the top of an ordinary pail, such as is em-3 5 ployed by janitors and others to contain water for scrubbingpurposes, and side bars la l0", integral with the curved body portion,parallel with each other and integrally connected by a cross-bar 10C.Ears 11 1l are formed on 4o and extend downwardly from the lower surface`of the center of the curved portion of the base-frame 10 and may beapertured transversely for the reception of a bolt or rivet (not shown)by means of which the base- ,45 frame may be attached to a pail. Holes12 12 and 13 13 are formed in the arms 10' 10" of the base-frame 10 andare provided for the reception o f bolts whereby said base-frame may befurther secured to a pail either o through the 'employment ofangle-irons or arms or side bars L l0b4 of the base-frame.

A short crank 2O is formed on one end of the shaft 9, and a long crank2l is formed on the opposite end of said shaft exactly opposite to andapproximately parallel with the short crank. The short crank isapertured transversely near its extremity, and a transverse aperture isformed in the long crank 21 direetlyopposite thereto and on a planeparallel with the axis of oscillation of the shaft. A knob 22. is formedon the extremity of the long crank 21. Ears 23 24 are formed on and risefrom the side bars 102L 10b of the baseframe 10 directly opposite eachother and on a plane parallel with the axis of oscillation of the shaft19, and said ears are apertnred transversely in alinementwith eachother. A rollershaft 25 is mounted for revolution in the apertures ofthe ears 23 24, and a roller 26, preferably made of wood, is mounted onsaid shaft. Longitudinally-slotted framefbars 26 27 are provided andarranged parallel with each other above the base-frame 10, with theirslots in horizontal alinement and traversed by the crank-shaft 19 andthe roller-shaft 25. Ears 28 29 are formed on and rise from the slottedbars 26 27 directly opposite each other and are apertured transverselyin alinement and on a plane parallel with the axis of oscillation of thecrank-shaft 19. A connecting-rod 30 is provided and formed with alaterally-bent end portion 3l, traversingthe aperture near the extremityof the short crank 20', and an end portion 32, bent laterally in anopposite directionfrom the portion 3l and traversing the aperture of theear 2S. Thus is the ear 28 secured to the short crank 20. Aconnecting-rod 33 is provided, with an end portion 34,

IOO

bent laterally and traversing the aperture in the long crank 2l, and a-nend portion 35, bent laterally in an opposite direction from the portion34 and traversing the aperture of the ear 29. Thus is the ear 29connected to the long crank 2l. The end portions of the connectingrods30 33 may be secu red against accidental release from their seats bykeys 36 or by riveting or other means of fastening. The rear endportions of the slots in the bars 26 27 are materially widenedvertically for the reception of expansive coil-springs 37 38, whichsprings bear at their rear ends against integral cross-heads 39 40 ofsaid bars. A roller-shaft 41 is mounted looselyin the slots of the bars26 27 and extends across the space between said bars at right anglesthereto and in a plane parallel with the axis of oscillation of thecrank-shaft19- A roller 42 is mounted on the shaft 41 between theslotted bars 26 27. Stems 43 44 are provided, with their body portionscircular in cross-section and mounted for rectilinear reciprocation inthe apertures formed in the centers of the cross-heads 3 9 and tiattenedportions integral with the body portions, but offset laterally therefromand into planes parallel therewith, which flattened portions areapertured to receive and embrace the extremities of the roller-shaft 41.The flattened portions of the stems 43 44 are `secured to the shaft 4lby keys 45 and lie against the outer faces of the bars 26 27,

` while the circular body portions of said stems are almost entirelyContained in the widened portions of the slots of the bars and traverseand support the expansive coil-springs. Conical hubs 46 47 are formed onthe stems 43 44 and enter the forward end portions of the expansivecoil-springs 37 38 thus limiting to a material degree the rattling orvibration of said springs and providing an endwise bearing or abutmentforeach spring in opposition to the cross-heads 39 40. 'lo prevent theinward withdrawal of the stems from their seats in the cross-heads, lhave provided keys 4S in the outer extremities thereof and arranged tobear at times against the outer faces of the cross-heads. Gathering-rods49 50 are provided and preferably made of wire, with laterally-bent endportions seated in the hori zontal apertures in the base-frame 10immediately below the normal open position of the shaft 4l, saidgathering-rods extending inwardly and obliquely to and traversing thebar 10c in front of and beneath the roller 26. It is the function of therods 49 50 to gather and retain a textile mop out of contact with thebars 26 27 or the side bars of the baseframe when said mop is compressedby the rollers.

In the practical operation of my mopwringer the parts are assembled andpositioned as illustrated in my drawings herewith and mounted on a pail,tub, or other receptacle for water. A textile mop carried by an ordinarymop-head on a mop-stick is introduced to the receptacle through thespace between the rollers 2G and 42 and is soused in water in thereceptacle until cleansed or wet to the desired degree. Then theoperator `withdraws the mop-head to a plane above either of the rollers26 42, grasps the knob 22 on the long crank 2l,and moves the sameupwardly and forwardly, as 'indicated by the arrow in Fig. l, to theextent of approximately one-half revolution of the crank-shaft 19, thelong and short cranks descendingin front of the standards 14 15 beyondthe dead-center. This movement of the crank-shaft applies a draft ont-he connecting-rods 30 and 33 and moves the slotted bars 26 27forwardly across the crank-shaft and the roller-shaft 25 and carries theroller 42 into close proximity with the roller 26 to a point ofapplication of pressure upon the mop. Upon approximating the rollerswithout the interposition of a mop the peripheries of said rollers wouldcontact before the cranks of the shaft 19 had fallen forwardly below thedead-center, and a further movement of said cranks would result in aslight compression of the expansive coilsprings 37 Thus aslight pressurewould be applied to a very thin mop introduced between the rollers 26and 42, and such pressu re would increase in intensityin direct ratio tothe increase of thickness of the mop interposed between the rollers; butat all times and under all circumstances the roller 42 will yield underthe resilience of the springs 37 f 38 sufficiently to permit of theabove-described forward falling of the cranks below the dead-center. Theoperator then withdraws the mop from between the rollers 26 and'42 andin so doing revolves those rollers in opposite directions and thoroughlywrings the water from the mop, the water falling into a receptacle onwhich the mop is mounted. It is to be understood that some means isprovided for retaining'the receptacle stationary during the operation ofdrawing the mop from between the rollers.
